NIA sources said the three officials have been asked
to appear before the NIA Deputy Superintendent of Police and
Chief Investigating Officer Jasveer Singh in Guwahati on
February 15.

Since August 2016, the NIA has been investigating
cases against various state government departments that
allegedly paid levies to Naga National Political Groups
(NNPGs) and seven government officials have been put under
trial in the case so far.

State government employees on November 21 last year
had brought out a rally here demanding immediate intervention
of the Central Government to withdraw the NIA and drop its
investigations against various departments

"The undisputed reality is that payments of tax to the
NNPGs are made not voluntarily nor willingly, but under
duress," said a memorandum of the Confederation of All
Nagaland State Services Employees' Associations submitted to
Governor P B Acharya on that day.
